Scientific American continues to produce the best coverage of science and the mind. The story on musicians and how they sync efforts is interesting. Thank you to Movietome Beta for the image of the album by The Police called Synchronicity.
I like the description on Wikipedia on synchronicity: Synchronicity is the experience of two or more events which are causally unrelated occurring together in a supposedly meaningful manner. In order to count as synchronicity, the events should be unlikely to occur together by chance. The concept does not question, or compete with, the notion of causality. Instead, it maintains that just as events may be grouped by cause, they may also be grouped by their meaning. Since meaning is a complex mental construction, subject to conscious and subconscious influence, not every correlation in the grouping of events by meaning needs to have an explanation in terms of cause and effect.
Jordan Lite's 60-Second Science blog, says, "Ever wonder how musicians manage to play in unison? Credit their brain waves: they synchronize before and while musicians play a composition, according to new research. German scientists report in BMC Neuroscience that they measured the brain waves of eight pairs of guitarists using electroencephalography (EEG) while they played a modern jazz piece called Fusion #1 (by Alexander Buck). The researchers found that the guitarists' brain waves were aligned most during three pivotal times: when they were syncing up with a metronome, when they began playing the piece and at points during the composition that demanded the most synchrony."
